The King and the Brave Little Mouse. The Magic Story Cloud, #12

When powerful King Adisa is captured by jealous enemies and locked inside a dark forest hut, he believes his story has come to a tragic end. Weak, hungry, and alone, the once-mighty ruler prepares to fight for survival in any way he can. But everything changes when a tiny grey mouse appears in the corner of the hut. At first, the desperate king considers the little creature as food. Yet a single moment of compassion changes both their lives forever.
To King Adisa's amazement, the mouse speaks-and promises to help him. Night after night, the brave little mouse returns with an army of loyal mice carrying grains, fruit, and bits of yam to keep the king alive. As the king regains his strength, a remarkable friendship grows between the mighty ruler and the smallest creatures imaginable. But when the enemy soldiers finally return, they discover something they never expected: the prisoner they left to die is standing tall and strong.
